OIL VALVE Filed June 22, 1928 fitter/mega Patented June 23, 1931 i l UNITED STATES PATENT FFIQE JOSEPH n. KILLIAN, or CHEYENNE, WYOMING om VALVE Application filed. June 22, i925. Serial no. 287,495.

This invention relates to an oil valve used opening in the steam valve or cylinder to in connection with mechanical forced feed which the valve is applied. lubricators of locomotives for supplying oil The lower section 7 is formed with a shoulto the valves and cylinders under steam pres der 9 to receive the valve seat 10 which is 5 sure, or while the throttle is shut off and the formed with an extension 11 defining a guide 55 engine is drifting. 1 for the valve stem 12 carrying the valve 13 The primary object of the invention is to atits lower end. As clearly shown by Figprovide a valve that will automatically open ure 2 of the drawings, the construction of and close after a predetermined quantity of the valve seat and valve is such that acomoil has been forced into the body of the valve, paratively small upper surface 14 is presented 6 the opening and closing of the valve being to the oil pressure, which one is admitted to controlled by the action of oil pressure on a the valve through the upper section of the small area of valve head againstthe minimum body portion, while a comparatively large and maximum working steam pressure of curved surface 15 is presented at the under- 15 the locomotive acting on the large area of the side of the valve. p I 65 valve head, thereby admitting oil to the cyl- An opening 16 1s provided in the valve seat inders. 11 and establishes communication between A further object of the invention is the prothe compartment 17 above the valve, and oil vision of a valve so constructed that the oil chamber 18 above the valve housing to the passing therethrough will be thoroughly end that oil may pass to the upper surface 14 t i d b th ti f th team to insure of the valve 13. Positioned on the valve seat the maximum degree of lubrication. and surrounding the extension 11, is a coiled With the foregoing and other objects in spring 19 that has its upper extremity restview which will appear as the description lng against the flange 20 of the cap 21 which 25 proceeds, the invention resides in the combiis held to the valve stem 12 by means of the nation and arrangement of parts and in the nut'22 whereby the tension of the spring 19 details of construction hereinafter described may be regulated to cause the valve to operand claimed, it being understood that changes ate under various pressures. in the precise embodiment of the invention At the upper end of the upper section of herein disclosed, may be made within the he body portion is an opening which is scope of What is claimed without departing threaded to accommodate the threaded exf 'th i it f th i ti tremlty of the pipe 28' that extends from the R f i t th d i force feed lubricator, so that oil under pres- Fi 1 i a i ill t ti th li sure wlll be admltted to the upper section of tion f the 1 the valve body, from where it passes to the Figure 2 is a longitudinal sectional view upper surface of the Valve, through the Open" thOl hth valve. g

If the engine is shut off and allowed to drift, the oil pressure in the oil chamber 18 will act to unseat the valve which is held in a seated position by spring 19, allowing the oil to pass into the lower section of the valve, whereupon the steam passing upwardly will mingle with the oil forcing it against the curved under surface of the valve 13 giving the oil a swirling motion from where it passes to the cylinders or valves in an atomized form. a

I claim:

A valve for force feed lubrication, comprising a valve housing, a removable valve seat mounted within the housing and dividing the housing into upper and lower compartments, said valve seat having an extension, a valve member including a valve stem, mounted within the extension, said valve engaging the valve seat to control the passage of oil through the valve, a. coiled spring surrounding the extension, a cap on one end of the valve stem and engaged by the spring to normally hold the valve seated, said valve seat having an opening to allow oil to pass therethrough, and inlet and outlet pipes connected with the housing.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signature.
